The T48 was a battle rifle tested by the U.S. military in the mid 1950s during trials to find a replacement for the M1 Garand. It was a license-produced copy of the Belgian FN FAL rifle. The rifle did not enter service, as the U.S. military decided to adopt the M14 rifle instead.

The M14 rifle, officially the United States Rifle, Caliber 7.62 mm, M14, is an American select fire battle rifle chambered for the 7.62×51mm NATO cartridge. It became the standard-issue rifle for the U.S. military in 1957, replacing the M1 Garand rifle in service with the U.S. Army by 1958 and the U.S. Marine Corps by 1965. The M14 was used by the U.S. Army, Navy, and Marine Corps for Basic and Advanced Individual Training from the mid-1960s to the early 1970s.
